INTRODUCTION: MYTH AND COSMOLOGY

Greek philosophical cosmology did not originate completely out of the blue. The first philosophical cosmologists - usually referred to as Ionian or Milesian cosmologists because they worked in Miletus, in Ionia - could react against, or sometimes build upon, popular conceptions that had existed in the Greek world for a long time. Some of these popular conceptions can be gleaned from the poetry of Homer and Hesiod (eighth century B.C.). In Homer the cosmos is conceived as a flat earth, surrounded by the Ocean (Okeanos), and overlooked by a hemispherical sky, with sun, moon, and stars. In the eighth century the annual course of the sun and the rising and setting of some constellations were integrated into a primitive seasonal calendar. Lunations were used for small-scale calendrical purposes (“the twenty-seventh of the month is best for opening a wine-jar” Hesiod Works and Days 814) and at some point - although there are no traces of this in Homer of Hesiod - some form of lunisolar calendar was established.
